"It's like the songs are going home in a way because a lot of the original thoughts and ideas that they were born out of were like this, and then we put the rock on it," Lee told AAP at the Sydney Opera House.

"So it does fit, it's sort of more like going to part of its origin."

Last year, Evanescence released Synthesis, their fourth album which, aside from two new songs, is a collection from the band's back catalogue recorded with an orchestra.

She also finally gets to be the sole voice on the band's massive 2003 hit, Bring Me To Life, which originally featured rapper Paul McCoy at the insistence of the band's label.

"I'm proud of Bring Me To Life but it's always been very funny to me (for it) to be recognised as the thing with the dude in it because it wasn't my idea, it wasn't really a part of who I felt we were, it was a compromise we had to make,"

"To take it back, just like a lot of the songs, and put them back to an origin place where they first came from ... it's like I can hear it like I've always wanted to hear it."
